Wyoming Pesticide Applicator Certification Practice Test

What does 'Crack-And-Crevice Application' involve during pesticide application?

1. Applying pesticides evenly across large open fields

2. Creating a barrier of pesticide around a building

3. Placing pesticide baits in cracks and crevices

4. Placing small amounts of pesticide into building cracks and crevices

The correct answer is: Placing small amounts of pesticide into building cracks and crevices

During a crack-and-crevice application, small amounts of pesticide are precisely placed into building cracks and crevices where pests commonly hide or travel. This method targets specific areas where pests are likely to be present, allowing for a more targeted and effective treatment while minimizing pesticide exposure to non-target organisms. This technique is particularly useful for controlling pests like cockroaches, ants, and other crawling insects that often seek refuge in tight spaces. The other options are not correct because: A. Applying pesticides evenly across large open fields involves a broadcast application method, which is not specific to crack-and-crevice treatment. B. Creating a barrier of pesticide around a building refers to perimeter treatment, which is different from crack-and-crevice application. C. Placing pesticide baits in cracks and crevices involves the use of bait stations rather than directly applying pesticide into the cracks and crevices.
